So I am using ng-repeat to list some information about an event, one of which is a date field. I would like to filter the dates, for example, be able to show events in the next 30 days. I am not sure what direction to take to acplish this.
<table>
<tr>
<th>Title</th>
<th>Description</th>
<th>Start Time</th>
</tr>
<tr ng-repeat="eventData in eventListData | orderBy:'+StartDateTime'">
<td>{{eventData.Title}}</td>
<td>{{eventData.Description}}</td>
<td>{{eventData.StartDateTime|date:'d MMM yyyy'}}</td>
</tr>
</table>

Reset to default 7First, the syntax for orderBy is wrong. It should be "orderBy:'+StartDateTime'" where +/- controls asc/desc direction, and 'StartDateTime' (mind single-quotes) is the field to pluck from.
Use timestamps for StartDate & do > now - < now + 30days, and then you have 2 options:
- Filter model array before it gets to your view
- Make a filter for angular & use it
I like the second option better, and I feel like it better fits with the spirit of angular, and allows more dynamic messing with the data. I made an example here
var app = angular.module('app', []);
// filter array by @field {String}
// return items from today to @days {Number} from now
// eg: events | upComing:'StartDateTime':30
app.filter('upComing', function(){
return function(items, field, days){
var timeStart = Date.now();
var timeEnd = Date.now() + (days * 86400000); // 1 day in ms
return items.filter(function(item){
return (item[field] > timeStart && item[field] < timeEnd);
});
};
});
app.controller('ctrl', function($scope){
// demo data, StartDateTime should be numbers in your data
$scope.eventListData = [
{
Title:'Event 1 (last in 30 dys)',
Description:'A cool Event',
StartDateTime: Date.now() + (86400000 * 5) // in 5 days
},
{
Title:'Event 2 (next)',
Description:'A cool Event',
StartDateTime: Date.now() + 86400000 // in a day
},
{
Title:'Event 3 (next next)',
Description:'A cool Event',
StartDateTime: Date.now() + (86400000 * 2) // in 2 days
},
{
Title:'Too-far-away Event',
Description:'A cool Event',
StartDateTime: Date.now() + (86400000 * 40) // in 40 days
},
{
Title:'Already-happend Event',
Description:'A cool Event',
StartDateTime: Date.now() - (86400000 * 2) // 2 days ago
}
];
});
and here is the HTML:
<html ng-app="app">
<head>
<meta charset=utf-8 />
<title>Angular Date Filter</title>
</head>
<body ng-controller="ctrl">
<table>
<tr>
<th>Title</th>
<th>Description</th>
<th>Start Time</th>
</tr>
<tr ng-repeat="eventData in eventListData | upComing:'StartDateTime':30 | orderBy:'+StartDateTime'">
<td>{{eventData.Title}}</td>
<td>{{eventData.Description}}</td>
<td>{{eventData.StartDateTime|date:'d MMM yyyy'}}</td>
</tr>
</table>
</body>
